Ranger 4WD V6-4.0L (2009)
-
Are the voltages greater than 10 volts?
Yes
GO to E4.
No
VERIFY the SJB fuses 9 (5A), 10 (10A) and 33 (5A) are OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E4 CHECK THE HS-CAN CIRCUITS BETWEEN THE IC AND THE DLC FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the IC C220b-1, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU), harness
side.
-
Measure the resistance between the IC C220b-2, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to E5.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E5 CHECK FOR CORRECT IC OPERATION
-
Disconnect all the IC connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the IC connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
